River bifurcation (Geomorphology 🏞️)

River bifurcation occurs when a river flowing in a single channel separates into two or more separate streams which then continue downstream. Some rivers form complex networks of distributaries, typically in their deltas. If the streams eventually merge again or empty into the same body of water, then the bifurca...

Knickpoint (Geomorphology 🏞️)

In geomorphology, a knickpoint or nickpoint is part of a river or channel where there is a sharp change in channel bed slope, such as a waterfall or lake. Knickpoints reflect different conditions and processes on the river, often caused by previous erosion due to glaciation or variance in lithology. In the cycle of erosion model, knickpoints advance one cycl...

Stream head cut (Geomorphology 🏞️)

In geomorphology, a stream head cut or simply head cut is an erosional feature of some intermittent and perennial streams. Headcuts and headward erosion are hallmarks of unstable expanding drainage features such as actively eroding gullies. Headcuts are a type of knickpoint that, as the name indicates, occur at the head of a channel. The knickpo...
